摘要
目前,熔模铸造工艺优化主要依托于经验试错,存在寻优周期长、人力成本高、操作效率低且缺乏算法优化等问题。构建了基于ProCAST有限元仿真软件和多任务批处理技术的熔模铸造工艺集成计算平台,该平台集成了试验设计算法(DOE)、有限元仿真、结果数据自动读写提取、近似模型构建、多目标优化协同工作等功能。以涡轮导向器为例,铸件缩松量为目标值,浇注温度、环境温度、热辐射率为设计变量,实现了铸造工艺-缺陷快速仿真集成优化。与传统仿真优化相比,使用集成计算平台效率提升了91.66%。
Currently,the optimization of investment casting processes heavily relies on empirical trial-and-error methods,resulting in long optimization cycles,high labor costs,low operational efficiency,and a lack of algorithmic optimization.Therefore,an integrated computing platform for investment casting processes was developed based on the Pro‐CAST finite element simulation software and multitasking batch processing technology,which integrates various functions,including Design of Experiments(DOE)algorithms,finite element simulation,automatic extraction of result data,surrogate model construction,and collaborative multi-objective optimization.Taking a turbine guide vane as example,integrated optimization of casting process-defect simulation was realized with shrinkage as target value,pouring temperature,ambient temperature and thermal emissivity as variables.The efficiency of integrated computing platform is improved by 91.66%compared with that of traditional simulation optimization.
